Abstract

Plants shape and interact continuously with their rhizospheric microbiota, which play a key role in plant health and resilience. However, plant-associated microbial community can be shaped by several factors including plant phenotype and cropping system. Thus, understanding the interplay between microbiome assembly during the onset of plant-pathogen interactions and long-lasting resistance traits in ligneous plants remains a major challenge. To date, such attempts were mainly investigated in herbaceous plants, due to their phenotypic characteristics and their short life cycle. However, only few studies have focused on the microbial structure, dynamic and their drivers in perennial ligneous plants. Ligneous plants coevolved in interaction with specific fungal and bacterial communities that differ from those of annual plants. The specificities of such ligneous plants in shaping their own functional microbial communities could be dependent on their high heterozygosis, physiological and molecular status associated to seasonality and their aging processes, root system and above-ground architectures, long-lasting climatic variations, and specific cultural practices. This article provides an overview of the specific characteristics of perennial ligneous plants that are likely to modulate symbiotic interactions in the rhizosphere, thus affecting the plant’s fitness and systemic immunity. Plant and microbial traits contributing to the establishment of plant-microbiome interactions and the adaptation of this holobiont are also discussed.

多年生木本植物健康中的根瘤微生物组组合、驱动因素和功能
植物塑造了根瘤微生物群落,并与其不断互动,而根瘤微生物群落在植物健康和恢复能力方面发挥着关键作用。然而,植物表型和耕作制度等多种因素会影响植物相关微生物群落。因此,了解植物与病原体相互作用开始时的微生物群集与木本植物持久抗性特征之间的相互作用仍然是一项重大挑战。迄今为止,由于草本植物的表型特征及其生命周期较短,此类尝试主要在草本植物中进行研究。然而,只有少数研究关注多年生木本植物的微生物结构、动态及其驱动因素。木本植物在与特定真菌和细菌群落的相互作用中共同进化,这些群落与一年生植物的群落不同。这些木质化植物在塑造自身功能微生物群落方面的特异性可能取决于它们的高度杂合性、与季节性相关的生理和分子状态及其衰老过程、根系和地面结构、长期的气候变异以及特定的文化习俗。本文概述了多年生木本植物的具体特征,这些特征可能会调节根圈中的共生相互作用,从而影响植物的适应性和系统免疫力。文章还讨论了有助于建立植物-微生物组相互作用的植物和微生物特征,以及这种全生物体的适应性。
